Of course, they come with their downsides, like forcing you to sacrifice creatures or losing life
For example, lets say [c]Sanguine Guard[/c] fights [c]Hired Poisoner[/c]

Path to Exile is the optimal removal for the deck (especially since we can sometimes eliminate the downside of giving our opponent a land with Leonin Arbiter), but Declaration in Stone is a fine budget replacement with some upside against token decks since it exiles all copies of a creature
It's as if we're seeing a freeze frame of its final terrifying moments
